Bug Description

Phatch bzr929 does not support 16 bit per channel TIFF images, and possibly any other 48bpp image format.

Sample 48bpp file: http://fileupl.com/down.php?i=lwtvpd&n=IMGP7504.tif

Phatch uses PIL as a backend, which does not support such images:
In [1]: import Image

In [2]: im = Image.open('IMGP7504.tif')

IOError: cannot identify image file

Also Phatch clearly states on its feature set that it only supports up to 32 bits.

So this is not a bug but a feature request. It might help if you find (python) image processing libraries which support 48 bit (imagemagick?!). We might integrate them in Phatch.

Thanks for reporting the bug anyway!
